sd-bus: enforce a size limit on D-Bus object paths

Replace stack with heap allocation. This avoids accessing/modifying
memory outside of the allocated stack region by sending specially
crafted D-Bus messages with very large object paths.

Vulnerability discovered by Chris Coulson <chris.coulson@canonical.com>,
patch provided by Riccardo Schirone <rschiron@redhat.com>.

CVE-2019-6454
